GALVANIC BATTERY.

SPECIFICATION formingpart of Letters Patent No. 290,149, dated December 11, 1883. Application filed June 26, 1883. (No model.) Patented in Belgium December 16, 1882, No. 59,879.

To ctZZ whom it may concern:

Be it known that we, J ULIUs UNGER, a citizen of the German Empire, residing at Gannstadt, Germany, and SAMUEL Orro EisnLn,

a citizen of the German Empire, residing at Heuchlingen, Germany, have invented new and useful Improvements in Galvanic Batteries, of which the following is aspecification.

This invention relates to improvements in i0 galvanic batteries, and has for its objects to provide an improved construction and ar rangement of the zinc and copper elements, to provide novel means for supporting the said elements at a certain distance apart, to provide means for simultaneously raising or adjusting all the elements, and to provide novel controlling apparatus for the battery. These objects we accomplish in the manner and by the means hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 shows a plan view of one element of the battery. Fig. 2 is a cross-section thereof.

The remaining figures will be referred to hereinafter.

Similar letters indicate corresponding parts.

The element, Fig. 1, consists of a copper dish, a, to which, at two. opposite rims, the

0 iron rods b are attached, over the ends of which rods 1) are placed small pieces of rubber hose to insulate them. The other two rims of the dish are each provided with two eyes, a, and the entire copper dish rests in a closely- 5 fitting zinc dish, d, which is provided with four small zinc strips, which pass through the eyes 0 and are bent over. By these means the zinc dish is'attached to the copper dish, so that they practically form one whole, and at 40 the same time can be easily renewed. On one side, between the two eyes 0, the edge of the copper dish is cut and bent outwardly, so that the bent portion,which reaches over the edge of thezinc dish, forms an outflow, as seen clearly 5 in Fig. 2. The different elements are placed one within the other, as seen in-Fig. 3, and by means of the supporting-links f, (one of which is shown in Fig. 4,) which catch or pass over the insulated ends of the iron rodsb, these elements are kept a certain distance apart,

since each of the lower rims, f, of each supporting or carryinglink strikes against the iron rodb of the element below. The eye or opening of the carrying-links f is of greater size than the thickness of the insulated end of the iron rods which enters such eye or opening, and the elements may be separated to the amount of this difference, so that when the uppermost dish or element is raised by any suitable means all the dishes or elements may successively be raised and drawn out of the fluid contained in the dish or element below. The drawings show a double battery, and the arms 9', Fig. 5, which raise the dishes of the lower series, are connected with the arms 9 of the upper series, so that on turning the eogwheel t, in which runs the screw-spindle h, the dishes of both series are raised simultaneously. To accomplish the raising easily, the

wheel i gears into the large wheel 4;, which sits on an axle, k, which can be turned by the crank-k. -The supporting-links f move in the guides an, connected to the wooden plate or table 2, (see Fig. 3 in side view, Fig. 5 in front view,) so that they cannot slipout or unlink. 7 5 The dishes or elements are so placed upon one another that the overflow alternately takes place first upon one side and then upon the other, so that in the subsequent pouring in. of water whichflows from the upper element to the lower ones the impregnated part of the fluid, when it is specifically heavier, does not flow along. Upon the wooden plate or table Z the controlling apparatus a (shown on a larger scale in face view, Fig. 6, and plan view, Fig. 7) is placed. The same is connected with the upper element by the rod 0 reaching into the element, and is put out of operation by said rod being raised when the upper element occupies its highest position--that is, when the battery is out of operation. In this case the rod 0 is raised by the bottom of the upper dish and moves the lever 19 in such a manner that the roll g on the arm 1) of the lever, which otherwise is held in position by a spring or weight, u, is lowered. Thepaper strip 1, which passes between the roll q and the roll t,which roll It sits firmly on the :axle or pivot s of the minute-hand of a time-piece, hangs loosely on the roll q when it is lowered, while, when the I00 battery is in operation, the paper strip is moved forward, The paper strip is divided by marks or lines, so that the time may be read during which the battery was in operation.

Fig. 3 shows the battery in side view in operation, and Fig. 5 shows the battery in front view out of operationthat is, the elements separated. In both figures the upper series is represented with the guide m, while said guides are broken off below.

To close the circuit, a copper dish, Figs. 1 and 2, is provided with a piece of copper wire, a, to which the conducting-wire x is attached in any suitable wayas, for example, by the binding-screws w.

Inasimple battery one conductor, w Fig. 3, is attached in the manner just stated, to the lowest dish, and the other conductor is attached to the uppermost dish in the manner shown in the lower part of Fig. 3. In a double battery corresponding dishes of the two batteries are first connected in the manner just described, and to the connecting wire or wires the conductors m a? may be attached, thus c011- necting corresponding dishes. XVithin the battery itself the current is not interrupted, as the zinc and copper dishes of each single element are in contact, and the elements among themselves communicate with one another through the electrolyte, which is poured into the cop per dish a, and into which dips the zinc dish dot the element above. The course of the cur rent is as follows: From the zinc dish (1 of the first or upper element it passes to the copper dish a of the next element through the electrolyte contained in the copper dish a of the second element, or the element directly under the first or upper element, and so on successively to the copper dish of the last or lowest element, from whence it passes, by the conductor to the conductor 00, which latter conat, having eyes 0 at its edges, with the zinc element d, having its edges provided with metallic strips engaging the eyes on the copper element, substantially as and for the purpose described.

2. In a battery, the combination of pairs of copper and zinc dishes at d, electrically connected, the supporting-arms I), having their ends covered with insulating material, the sus pendinglinks f, the guides on, and adjusting mechanism h i a", substantially as described.

3. The combination, with the copper and zinc elements, of the controlling apparatus composed. of a rod, 0, lever 12, carrying the friction-roll q, the actuating-roll t, and strip 1*, passing between the said rolls and axis or pivot s of a time-piece, substantially as described.

4. A controlling apparatus provided with an actuating-wheel, t, a lever, ;,having an arm, 1), a friction-wheel, q, mounted on the arm of the lever, and rod 0, for adjusting said lever and the friction-wheel, substantially as and for the purpose set forth.

In testimony whereof we have hereunto set our hands and seals in the presence of two subscribing witnesses.
